Type 65 Coupe Update: E-Brake Handle, Fitting the A/C and More IRS – and Maker Faire 2013 Application   Leave a comment

I got tired of fiddling with the IRS so I did something different this weekend. Here is a picture of the E-brake ratchet handle that comes with the Complete Kit. Since the parts are plain, un-finished steel, I decided to paint it to prevent rust. The exploded view in the instructions make assembly very easy. I wish The Factory would include an exploded view for the IFS as well as the IRS – makes things go so much better. The finish is white and black appliance epoxy from Rustoleum.

Here are some pictures. . .

I am not sure if I like the location of the E-brake handle, it is on the passenger side of the transmission hump. A popular modification is to use a Pontiac Fiero unit and re-locate it closer to the driver. We’ll see if I want to change this setup. (The sharp-eyed people will notice the e-brake handle is backwards. . . . . . )

Here are some images of the air conditioner and a cardboard aided design (CAD) templates I am making. This requires some cutting of the dashboard and firewall, so I want to mock everything up before I start cutting. I have some very sturdy aluminium plates for the A/C baseplate, and some sheet aluminum for the enclosure. A CAD version will be made first, then transferred to aluminum.

Moving back to the IRS, I received some advice from the veteran builders, and so here is what I did to the lower control arm mounts. The shims (thin black steel washers) F5R supplies are slipped into place and some adjustment is done by placing shims here and there. However, it makes more sense to limit the toe and camber adjusters so that the tweaking can be as simple as possible. By “fixing” one side of the control arm, and limiting it to one adjuster for toe and one adjuster for camber, alignment is simplified and less time consuming.

Currently, this stage is to just “eyeball” the adjustments, and continue the build process. Wheel alignments – both front and rear – may be done after the wheels and tires are mounted. (Probably can be done at the “go kart” stage, when the chassis is complete and the engine, drivetrain, electrics and brakes are installed and running.)

Here are some pictures. As this step gets closer to completion, I will add more details for future reference.

Above right: Here is the trick I use to install slippery washers, shims and spacers onto things – Use a punch or some other tool to poke through the stack of parts together, thus aligning the holes of each part. Then . . .

. . . push the fastener – and the punch – through the stack of parts. Wiggling, pushing and pulling will help. Sometimes a quick-clamp can help, too.

Maker Faire 2013 Update: Application is In!

I turned in an application for Maker Faire Bay Area 2013. Our Maker name is “Not Your Grandpa’s Ham Radio 2” and we will continue the theme my team entered last year. We will have some new projects on display, and we will bring some of the more popular items from last year. Here is a look at some of our projects from last year – as well as some other interesting and amazing things I saw last year.
